Through partnerships with Renren and Tencent Weibo, Cooliris, a Silicon Valley-based photo viewing and management service, has achieved combined growth with over 50x increase in user acquisition in China. Beyond pure acquisition, engagement of those users increased significantly as well, with over 20% of Chinese users returning to the app on a weekly basis.

Based on the huge user base, Cooliris discovered that the audiences from these two different social networking platforms behaved quite differently in terms of photo consumption and sharing. Time spent and photos viewed per person in Tencent Weibo doubled that in Renren, but Renren photos are being shared 50% more than Tencent photos.

Cooliris said that users are spending more time and viewing more photos in Tencent due to the curated public feed of photos (consumption intent), but users are sharing and starting conversations about Renren photos because the users on the platform have more personal relationships with each other (sharing intent).
